thanks, checked Kurt's review of course, he seems to think it almost equivalent to CZ when stopped down...

... and his reviews have proven to be very accurate.

But his review still uses the A900...

Both the a99 and the a900 have very high quality 24MP 35mm FF sensors. At the lower ISO's, were testing took place, I would think the results would be very similar. High ISO would be a different story but thats hardly relevant to the lens discussion. At any rate, I was wondering about what you meant by that comment.
